C Rating Explained
The C rating indicates how fast a battery can discharge.
Formula
Max Current = C Rating × Capacity (Ah)
Example: 100C × 1.3Ah = 130A
Burst vs Continuous
Does Higher C Mean Better?
Not always. Higher C batteries are heavier and more expensive. Match the C rating to your drone's actual current draw.
